Silk.NET VS ComputeSharp

A couple other options than what has been suggested so far: - TerraFX.Interop.Windows. Raw, blittable, 1:1 bindings for all Win32, D2D/D3D11/D3D12 APIs (there's also a version with Vulkan bindings). As close to doing #include as you can get in C#. This is my personal favorite, I use it in my own ComputeSharp library, and transitively we use it in the Microsoft Store too 🙂 - Silk.NET another version of high-performance bindings, more opinionated than TerraFX and with some additional helpers to make it a bit easier to use.

Here is an example of using "releases" in GitHub: https://github.com/dotnet/Silk.NET/releases. Most repositories use releases and releases seem like they wpuld be appropriate for your repository too.

I've been looking at this. Is this similar to the UrhoSharp project you talk about? https://github.com/dotnet/Silk.NET

Have you looked at Silk.NET before?

Take a look at https://github.com/dotnet/Silk.NET . You should be able to use your existing rendering context with it. So you could use something like imgui (They have bindings for that) to render your UI. Or if you just start writing your rendering code, you could consider writing the whole rendering engine with it. I used it in the past for a game engine and performance is no problem for most of the usecases.

If you want something more ".NET like", check out Silk.NET instead. It's also community maintained and in the .NET Foundation, but does name remappings, friendly API overloads, and other things that make it feel more ".NET like": https://github.com/dotnet/Silk.NET

A hello world .NET console app with NativeAOT is 1.08 MB. Goes down to 1.08 MB with some tweaking. Goes below 1MB with more tweaking. I have a fully self-contained NativeAOT sample app that renders some fancy animated shaders with DX12 that's about 2MB in size.

I dont think it's exactly what you're looking for, but I've found ComputeSharp to be a great C# GPU tool

Here's some: - MVVM Toolkit - PolySharp - ComputeSharp

If you don't mind being Windows only, I would also recommend trying out (shameless plug) ComputeSharp. You can find it on NuGet and it's available for UWP and WinUI 3 as well with ready to use XAML controls. The point is that it would allow you do your entire rendering via pixel/compute shaders, so it could basically run entirely on the GPU. That'd allow you to render even millions of particles with pretty good performance 🙂

Create a UWP or WinUI 3 applicaation and use the AnimatedComputeShaderPanel from ComputeSharp. The library lets you write shaders (ie. code to run on the GPU) entirely in C#, and handles all the logic to setup a DX12 animated swapchain, similar to Win2D. If you look at the repo you can also see a whole bunch of examples, which you can also try out for yourself. There's also several wiki pages with lots of info.
